I do this currently with a powershell script

function check-chassis {
BEGIN {}
PROCESS {
$computer = "$_"
$chassis = Get-WmiObject win32_systemenclosure | select chassistypes
if ($chassis.chassistypes -contains '3'){Write-Output "Desktop"}
elseif ($chassis.chassistypes -contains '4'){Write-Output "Low Profile Desktop"}
elseif ($chassis.chassistypes -contains '5'){Write-Output "Pizza Box"}
elseif ($chassis.chassistypes -contains '6'){Write-Output "Mini Tower"}
elseif ($chassis.chassistypes -contains '7'){Write-Output "Tower"}
elseif ($chassis.chassistypes -contains '8'){Write-Output "Portable"}
elseif ($chassis.chassistypes -contains '9'){Write-Output "Laptop"}
elseif ($chassis.chassistypes -contains '10'){Write-Output "Notebook"}
elseif ($chassis.chassistypes -contains '11'){Write-Output "Hand Held"}
elseif ($chassis.chassistypes -contains '12'){Write-Output "Docking Station"}
elseif ($chassis.chassistypes -contains '13'){Write-Output "All in One"}
elseif ($chassis.chassistypes -contains '14'){Write-Output "Sub Notebook"}
elseif ($chassis.chassistypes -contains '15'){Write-Output "Space-Saving"}
elseif ($chassis.chassistypes -contains '16'){Write-Output "Lunch Box"}
elseif ($chassis.chassistypes -contains '17'){Write-Output "Main System Chassis"}
elseif ($chassis.chassistypes -contains '18'){Write-Output "Expansion Chassis"}
elseif ($chassis.chassistypes -contains '19'){Write-Output "Sub Chassis"}
elseif ($chassis.chassistypes -contains '20'){Write-Output "Bus Expansion Chassis"}
elseif ($chassis.chassistypes -contains '21'){Write-Output "Peripheral Chassis"}
elseif ($chassis.chassistypes -contains '22'){Write-Output "Storage Chassis"}
elseif ($chassis.chassistypes -contains '23'){Write-Output "Rack Mount Chassis"}
elseif ($chassis.chassistypes -contains '24'){Write-Output "Sealed-Case PC"}
else {Write-output "Unknown"}

}
END{}
}

$obj = new-object -com wscript.shell

$tmp = "localhost" | check-chassis

If (($tmp -like "Laptop") -eq "True") {
Start-Process wsa.bat -Wait
}
If (($tmp -like "Notebook") -eq "True") {
Start-Process wsa.bat -Wait
}

This definitely needs to be implemented somewhere down the line. I'm using a WMI query in my batch files that's checking against a steadily growing list of machine names - this is going to be unmanageable sooner rather than later, especially as the number of tasks that use this grow.
